Apple recommends replacing your affected hard drive as soon as possible. Before you go in for service, please back up your data. Learn more about backup options.Additional Information

You will need to have the original Mac OS installation discs that were shipped with your iMac in order to reinstall your operating system, other applications, and any backed up data after your hard drive is replaced.

This worldwide Apple program does not extend the standard warranty coverage of the iMac.

Apple will replace affected 1TB Seagate hard drives, free of charge, for three years from your iMac’s original date of purchase or until April 12, 2013, whichever provides longer coverage for you. Apple will continue to evaluate service data and provide extensions to this program as needed.
